[Purpose/significance]It was important for information retrieval course to reflection, reorientation and explore the case-based teaching method in the digital age. [Method/process] Method of comparative study and historical analysis were employed in the paper. The article unscrambled the course history, and discussed the current teaching objectives and the application of case-based teaching method, then studied how to design the retrieval cases in information retrieval course from three aspects: case angle, case level and case ratio. [Result/conclusion] The lifeline of information retrieval course was to develop students' thinking ability and construct their thinking space, and case-based teaching method was useful for the teaching objectives. Chosen keywords were the suitable joint of case-based teaching method applied in information retrieval course, which could mesh other searching methods.
